Lime Rotary Kiln Manufacturer | Efficient Lime Calcination Solutions

Working Principle

A lime rotary kiln is a cylindrical, slightly inclined, slowly rotating furnace used for limestone calcination and quicklime production. Its core components include the kiln body, feeding and discharging devices, burner system, electric apparatus, instrument control system, and dust removal units.

Limestone is fed into the kiln at the upper end and gradually moves downwards as the kiln rotates.
Fuel is burned at the kiln head, and the heat is transferred to the limestone through radiation, convection, and conduction.
The limestone undergoes a chemical reaction, releasing CO₂ and converting into quicklime at high temperatures.
High-temperature flue gas is treated through the kiln tail dust removal system, ensuring environmental compliance.

Active Lime Production Line

An active lime production line converts limestone into high-quality active lime through controlled calcination. The complete production process includes limestone crushing, screening, preheating, calcination, cooling and product conveying.

Our lime rotary kiln serves as the key equipment in the calcination stage, ensuring efficient heat transfer, stable temperature control and consistent lime quality.
